a of which the machine can be operated at a minimum cost, and accomplishthe desired results in a quick and efficient manner.

In carrying out the invention I provide the agitator with a plurality ofangularly shaped to pivoted blades which are automatically rockedincident to the oscillation of the agitator, thereby promoting thecirculation of water, directing it upwardly and through the clothes, andalso turning the clothes over is in the machine at more frequentintervals.

The nature and advantages of the invention will be better understoodwhen the following detail description is read in connection with theaccompanying drawings, the

invention residing in the construction, combination and arrangement ofparts as claimed. In the drawings forming part of this application likenumerals of reference indicate similar parts in the several views, andwhere- 1n: 7

Before entering into a detailed description of what is hereinillustrated, I desire to have it understood that the machine forming thesubject matter of the present invention can be constructed from anysuitable material, and also vary in size and design without departingfrom the inventive idea.

The machine essentially includes a casing 10 preferably mounted uponcasters 11 so that the machine can be conveniently moved from place toplace. The casing is provided with spaced upper and lower bottoms 12 and13 respectively, and the space between these bottoms define acompartment for the transmission mechanism to be hereinafter described.The bottom 12 is formed with a marginal flange 14, while movablysupported upon this bottom is the agitator as clearly illustrated inFigure 1.

The agitator is in the nature of a shallow receptacle including a bottom15 and a vertical wall 16, while rising from the bottom 15 is acentrally located hub-like portion 17. Pivoted between the vertical wall16 and the hub-like portion 17 are angular shaped blades indicatedgenerally at 18, and while any number of these blades may be employed ina single machine, they are equidistantly spaced apart as clearlyillustrated in Figure 2. Furthermore, the angularity or cross sectionalconfiguration of each blade may vary without departing from theinventive idea, but these blades are preferably of substantiallyV-shaped formation in cross section as clearly illustrated in Figure 4,and the outer edges of the respective branches of each blade arepreferably curved outwardly as indicated at 19.

As hereinabove stated these blades are freely pivoted, and are adaptedto be automatically tilted incident to the oscillatory movement of theagitator in its entirety, and consequently during the operation of themachine, these blades shift from the position shown by full lines inFigure 4 to the dotted line position illustrated in the same figure, andin this manner the circulation of the water in the machine is materiallypromoted. In other words the water is not only circulated and agitatedin all directions, but particularly forced in an upward direction byreason of the configuration of the blades, and thereby forced throughthe clothes. By the construction and arrangement of the blades and thefact that they continuously tilt from one side to the other, incident tothe oscillatory movement of the agitator in its entirety, the clothesare also turned overat more frequent intervals, than in machines of theclass in question, with which I am familiar.

bearing 22 The shaft however includes a cylindrical portion 21 whichoperates in a suitable boss or secured to the bottom 12 of the agitator.

shaft 18 bored to receive the power driven shaft 23, the latter havingassociated therewith the member 24 of a suitable clutch. The cooperatingmember 25 of the clutch is slid ably mounted upon the cylindricalportion of the agitator shaft as illustrated in Figure 1, and is movedinto and out'of engagement with the clutch member 24 by means of a lever26 which is fulcrumed atan appropriate point in its length as at 27.This lever moves through a slot 28 formed in the casing 10 and isconnected by means of a link 29 with a manipulating handle 30. Theclutch is held in either of its given positions by a suitable pawl andratchet construction associated with the handle 30 as illustrated inFigure 1.

Located within the casing 10 beneath the bottom 12 is a housingindicated generally at 31 for the transmission mechanism, and thismechanism/includes a horizontally disposed gear32 which meshes with aworm gear 33 forming part of a shaft 34 which is,

rotated by a motor 35 through the instrumentality of a belt 36 asclearly illustrated in Figure 3. Arranged above the gear 32 andassociated wlth the shaft 37 are eccentrics 38 and 39 respectively andthese are connected with the arms 40 and 41 respectively which projectlaterally from the motor driven shaft 23 as clearly shown in Figure 7.R0- tated from one end of the shaft 34 is a vertical shaft 42 which maybe utilized to operate.

a wringer or the like. The construction and arrangement of parts notonly equalizes load noises, but results in the construction of a machineof the class in question which can be operated with a minimum of powerand expense', and employing a minimum number of parts.

In practice, the operation of the agitator can be quickly andconveniently controlled through the clutch mechanism above described.and whenthe agitator is oscillated from the power driven shaft 23, theangular shaped blades 18 are rocked in reverse directionsand therebydirect the water upwardly through the clothes and keeps the latterconstantly in motion, turning the clothes over at frequent intervals.

While it is believed that from the fore going description the nature andadvantages of the invention will be readily understood,

I desire to have it known that I do not limit myself to what is hereinshown and described, andthat such changes may be re- This cylindricalportion of the pivoted between -a casing, a receptacle-like agitatorsupported therein, means for oscillating the agitator, and a pluralityof horizontally disposed blades angular in cross section, freely pivotedwithin the receptacle and adapted to be automatically rocked incident tothe oscillatory movement of the receptacle.
